Member Function Documentation

static ReturnType compute ( SGMatrix< T A,
SGMatrix< T B 
)
static

Performs the operation C = A .* B where ".*" denotes elementwise multiplication.

This version returns the result in a newly created matrix. If elementwise-product is desired that will work irrespective of the backend and the matrix type used, then this method should be used.

Parameters
AFirst matrix
BSecond matrix
Returns
The result of the operation

Definition at line 93 of file ElementwiseProduct.h.

static void compute ( SGMatrix< T A,
SGMatrix< T B,
SGMatrix< T C 
)
static

Performs the operation C = A .* B where ".*" denotes elementwise multiplication.

This version should be used for backend specific code requirements. For example, use this with CGPUMatrix and explicitly set ViennaCL backend, or SGMatrix and explicitly set Eigen3 backend. If matrix-type/backend-type independent code is desired, use the version that does not support preallocated result matrix but returns the result in a newly created matrix instead.

Parameters
AFirst matrix
BSecond matrix
CResult of the operation
